FTI consulting, page-17

I have professional indemnity insurance and it's checked by clients. Whether or not the consultant has PI, the client can still sue them if errors have been made in their submission, just PI will stop you going bankrupt very quickly. I feel like there's a lot hanging on whether there's a case to be made against the mineral resource analysis consultant; it seems their information was definitely erroneous but maybe they have some kind of blanket disclaimer saying that the information is only provided as an estimate and no responsibility will be accepted for errors? Otherwise, surely Calidus themselves or at least the administrators would have pursued them for damages?
